Scope
Quality:
The fire hose assembly supplied under this spec-
ification shall be constructed with superior quality materials.
NFPA 1961 standards shall be observed in production of the
assembly, in order to ensure its quality and durability.
Service Life:
Hose furnished under these specifications
will have a potential service life
warranty of not less than
ten years
; barring mistreatment that would render it unfit
for service. Upon delivery, the hose shall be free from
defects in workmanship and materials. Any defective hose
will be replaced at no charge whatsoever.
a
Jacket Construction
The jackets will be woven evenly and be free of defects,
including knots, lumps, or unsightly disfigurations that
could jeopardize the integrity of the hose assembly. The
warp yarn shall consist of staple polyester yarn. The use of
filament or entangled yarn is expressly forbidden due to
the lack of inherent abrasion resistance. The filter yarns
shall be constructed of high strength, low elongation, fila-
ment polyester to reduce weight and increase flexibility.
a
Abrasion Impregnation
Hose assemblies are available with polymer impregnation
that provide additional abrasion resistance. Colors include:
yellow, orange, red, tan, black, blue and green. Color shall
be pure and even in each hose. Impregnated hose shall
meet the requirements of Mill-H-24606B for abrasion
resistance.
a
Lining
The rubber lining shall be a single-ply extruded tube of
synthetic EPDM compounded to resist ozone. The finish
form shall be free of pits or other imperfections and have
a smooth finish. No reclaimed rubber shall be used. Plastic
tubes that sacrifice durability of the hose life for the sake
of weight are not acceptable.
Backing:
The backing shall be of adequate thickness to
create a smooth waterway but not greater than .020. The
fire hose constructed under this specification shall be man-
ufactured fully backed using a calendered EPDM. The use
of adhesives of any kind are acceptable and expressly for-
bidden.
Tensile Strength & Ultimate Elongation:
Shall
meet the standards of Underwriters Laboratories, Inc.
TM
as
well as all other properties of UL-19 for rubber lined
hoses. A valid U.S. Underwriters inspection procedure
shall be in force.
